<h1>分页</h1>

<ul>
<li><a href="#configuration">配置</a></li>
<li><a href="#usage">用法</a></li>
<li><a href="#appending-to-pagination-links">分页链接附加</a></li>
</ul>


<p><a name="configuration"></a></p>

<h2>配置</h2>

<p>在其他框架中，分页可能是非常痛苦的。Laravel 使它变得很轻松。在 <code>app/config/view.php</code> 文件中有一个配置选项。<code>pagination</code> 选项指明哪个视图用来生成分页链接。默认情况，Laravel 包含两个视图。</p>

<p><code>pagination::slider</code> 视图将显示一个智能的基于当前页码的范围的链接，另一个 <code>pagination::simple</code> 将简单显示 "previous" 和 "next" 按钮。<strong>这两个都可以立即适用于 Twitter Bootstrap。</strong></p>

<p><a name="usage"></a></p>

<h2>用法</h2>

<p>有好几种方法产生分页，最简单的的是在一个查询构建器或 Eloquent 模型中使用 <code>paginate</code> 函数：</p>

<p><strong>数据库查询结果分页</strong></p>

<pre><code>$users = DB::table('users')-&gt;paginate(15);
</code></pre>

<p>您也可以对 <a href="/docs/eloquent">Eloquent</a> 模型进行分页；</p>

<p><strong>Eloquent 模型分页</strong></p>

<pre><code>$users = User::where('votes', '&gt;', 100)-&gt;paginate(15);
</code></pre>

<p>传递给 <code>paginate</code> 函数的参数是您希望每页显示项目的个数。一旦您获取了结果，您可以在视图中显示它们，并使用 <code>links</code> 函数产生分页链接：</p>

<pre><code>&lt;div class="container"&gt;
    &lt;?php foreach ($users as $user): ?&gt;
        &lt;?php echo $user-&gt;name; ?&gt;
    &lt;?php endforeach; ?&gt;
&lt;/div&gt;

&lt;?php echo $users-&gt;links(); ?&gt;
</code></pre>

<p>以上便是产生一个分页的全部过程！注意我们没有必要告诉框架当前的页面，Laravel 将会帮我们自动检测。</p>

<p>您也可以通过以下函数获取其他分页信息：</p>

<ul>
<li><code>getCurrentPage</code></li>
<li><code>getLastPage</code></li>
<li><code>getPerPage</code></li>
<li><code>getTotal</code></li>
<li><code>getFrom</code></li>
<li><code>getTo</code></li>
</ul>


<p>有些时候，您可能希望通过传递一个选项数组手动创建一个分页实例。您可以使用 <code>Paginator::make</code> 函数实现这个功能：</p>

<p><strong>手动创建一个分页</strong></p>

<pre><code>$paginator = Paginator::make($items, $totalItems, $perPage);
</code></pre>

<p><a name="appending-to-pagination-links"></a></p>

<h2>分页链接附加</h2>

<p>您可以在分页类上使用 <code>appends</code> 函数在分页链接中附加查询字符串：</p>

<pre><code>&lt;?php echo $users-&gt;appends(array('sort' =&gt; 'votes'))-&gt;links(); ?&gt;
</code></pre>

<p>这将产生如下所示的 URL：</p>

<pre><code>http://example.com/something?page=2&amp;sort=votes
</code></pre>
